A permeability and free-volume study in chlorinated poly[(1-trimethylsilyl)-1-propine] membranes
Permeability and positron annihilation measurements were carried out on PTMSP membranes, before and after chlorination. It is found that permeability decreases in the chlorinated films; this can be correlated to the microscopic free volume decrease as probed by positronium. Effect of aging is also investigated.
